Sky Studios and BBC Arts are both losing a senior commissioner, with each exec leaving after many years.
Sky Studios director of comedy Jon Mountague has been with the broadcaster for more than a decade, commissioning shows such as Brassic, Breeders, Funny Girl, In the Long Run and Stella, and Christmas specials such as Roald & Beatrix and The Amazing Mr Blunden. 
Mountague has also sought to bring new and diverse talent to Sky through Sky Comedy Shorts and Sky Comedy Rep, which supports new writing talent in partnership with the Birmingham Rep.
He stands down at the end of this month but will continue to support existing projects for the rest of this year. His next move is not yet known, but he plans to stay within TV.
Sky has not yet confirmed plans to find a successor.
Meanwhile BBC Arts commissioning editor Emma Cahusac is leaving the corporation after eight years to go freelance.
A former Channel 4 arts commissioner, producer of The Culture Show, and development head at Oxford Scientific Films, Cahusac oversaw returnable arts formats including Cactus TV’s BBC2 book review show Between the Covers and Chatterbox’s BBC1 series Extraordinary Portraits.
She also ordered Windrush: Portraits of a Generation from BBC Studios, and ClearStory’s African Renaissance.
BBC head of arts Suzy Klein said: “Emma has been a great advocate for the arts and for meaningful representation and diversity in television, and we wish her the best of luck in the freelance world.”
Cahusac’s exit was first reported by Broadcast.
